Calibrachoa plant named ‘Balcabinstim’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Balcabinstim’, characterized by its deep reddish-purple colored flowers having a white coloration forming a central star pattern, medium green-colored foliage, and moderately vigorous, mounded-trailing growth habit, is disclosed.

Latin name of genus and species of plant claimed: Calibrachoa x hybrida.

Variety denomination: ‘Balcabinstim’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCalibrachoa plant botanically known as Calibrachoa x hybrida andhereinafter referred to by the cultivar name ‘Balcabinstim’.

The new cultivar originated in a controlled breeding program inGuadalupe, Calif. during September 2018. The objective of the breedingprogram was the development of Calibrachoa cultivars with attractivenovelty flower coloration, and a moderately vigorous, mounded-trailinggrowth habit.

The new Calibrachoa cultivar is the result of cross-pollination. Thefemale (seed) parent of the new cultivar is the proprietary Calibrachoax hybrida breeding selection coded CAL-15903-02, not patented,characterized by its dark fuchsia-colored flowers having a whitecoloration forming a central star pattern, medium bright-green coloredfoliage, and vigorous, mounded-trailing growth habit. The male (pollen)parent of the new cultivar is the proprietary Calibrachoa x hybridabreeding selection coded CAL-16003-01, not patented, characterized byits medium pink-colored flowers having a white coloration forming acentral star pattern, medium green-colored foliage, and moderatelyvigorous, mounded-trailing growth habit. The new cultivar was selectedas a single flowering plant within the progeny of the above statedcross-pollination during March 2019 in a controlled environment inArroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings sinceMarch 2019 in Arroyo Grande, Calif. and West Chicago, Ill. hasdemonstrated that the new cultivar reproduces true-to-type with all ofthe characteristics, as herein described, firmly fixed and retainedthrough successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedlyobserved and can be used to distinguish ‘Balcabinstim’ as a new anddistinct cultivar of Calibrachoa plant:

-   -   1. Deep reddish-purple colored flowers having a white coloration        forming a central star pattern;    -   2. Medium green-colored foliage; and    -   3. Moderately vigorous, mounded-trailing growth habit.

Plants of the new cultivar differ from plants of the female parentprimarily in having lighter reddish-purple colored flowers with a morepronounced star pattern and reduced growth vigor. Plants of the newcultivar differ from plants of the male parent primarily in havingdarker reddish-purple colored flowers.

Of the many commercially available Calibrachoa cultivars, the mostsimilar in comparison to the new cultivar is CABARET Pink Star‘Balcabinsta’, U.S. Plant Pat. No. 28,462. However, in side-by-sidecomparisons, plants of the new cultivar differ from plants of‘Balcabinsta’ in at least the following characteristics:

-   -   1. Plants of the new cultivar have darker reddish-purple colored        flowers than plants of ‘Balcabinsta’;    -   2. Plants of the new cultivar have flowers with a whiter central        star pattern than plants of ‘Balcabinsta’; and    -   3. Plants of the new cultivar have smaller diameter corollas        than plants of ‘Balcabinsta’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonablypossible to make the same in color illustrations of this type, typicalflower and foliage characteristics of the new cultivar. Colors in thephotographs may differ slightly from the color values cited in thedetailed description, which accurately describes the colors of‘Balcabinstim’. The plants were approximately 5-months old. The plantswere grown in 3-gallon containers for approximately 10 weeks in anoutdoor nursery in West Chicago, Ill. Plants were pinched twice prior totransplant.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmentalconditions to date. Accordingly, it is possible that the phenotype mayvary somewhat with variations in the environment, such as temperature,light intensity, and day length, without, however, any variance ingenotype.

The chart used in the identification of colors described herein is TheR.H.S. Colour Chart of The Royal Horticultural Society, London, England,2015 edition, except where general color terms of ordinary significanceare used. The color values were determined in August 2021 under naturallight conditions in Naperville, Ill.

The following descriptions and measurements describe approximately5-month-old plants produced from cuttings from stock plants and grownunder conditions comparable to those used in commercial practice. Theplants were grown in 3-gallon containers for approximately 10 weeks inan outdoor nursery in West Chicago, Ill. Plants were given two pinchesprior to transplant. Prior to transplant plants were grown in apolycarbonate greenhouse in West Chicago, Ill. Greenhouse temperatureswere maintained at approximately 70° F. to 85° F. (21° C. to 29° C.)during the day and approximately 60° F. to 70° F. (16° C. to 21° C.)during the night. Supplemental lighting was used during propagationstage. Measurements and numerical values represent averages of typicalplants.
